DeMarco Murray occasionally looks like a breakout star at running back, but the Dallas Cowboys have been unable to get him going since Week 1.

Jon Gruden spoke of the Cowboys identity offensive during their nineties dynasty.

"That's what the Cowboys were, in my opinion, when they were great," said Gruden of the Cowboys' big offensive line that would create holes for Emmitt Smith. "They would mash you with the running game, then Troy Aikman would rip you (with play action to their receiving options)."

The Cowboys rushed for just 41 yards on 14 attempts against the Bears.

"This offensive line is just coming together," said Gruden. "There is no balance in this offense right now."
